September 22, 2022Silver doesn’t oxidize, though; it tarnishes, which is the same as saying that it forms a patina. Tarnish is formed when sulfur or sulfur compounds come into contact with silver.

- Why has my silver turned black? Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. Silver oxidizes faster in places with a lot of light and high humidity.
- Does Brighton tarnish? Each piece is cast in solid brass or zinc alloy and is plated in pure silver. Since silver has a natural tendency to tarnish (oxidize) and scratch, we add a protective layer of lacquer to assist in retarding this natural process.
- What is the black stuff that comes off silver? Possible explanations why silver oxidizes? Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. Silver oxidizes faster in places with a lot of light and high humidity.
- What happens to silver as it ages? Over time, any sterling silver jewelry exposed to air will tarnish. Comprised of 92.5% silver and 7.5% other metals. It's the other metals, typically copper, that make sterling silver tarnish. The copper reacts to moisture and sulfur in the air, causing the sterling silver tarnish.
- Does vinegar oxidize brass? Salt and Vinegar Malt, white wine or cider vinegar all work well. The acidity causes the brass to rapidly oxidize, the process that tarnishes brass over time. Leave overnight, then rinse thoroughly before drying with a soft cloth. You could also soak brass items in the salt and vinegar mixture.
- Does silver deteriorate over time? Silver is stable in pure air and water, though it tarnishes quickly when exposed to air that contains elevated levels of ozone, hydrogen sulfide or sulfur. (In the past 200 years, the amount of sulfur in the atmosphere has increased, so silver tarnishes more quickly than it did in pre-Industrial times.)
